Yes we are, since a couple of months.

$ git grep -l SSEi_REVERSE_STEPS *fmt*c
mssql-old_fmt_plug.c
mssql05_fmt_plug.c
mssql12_fmt_plug.c
nt2_fmt_plug.c
rawMD4_fmt_plug.c
rawMD5_fmt_plug.c
rawSHA1_fmt_plug.c
rawSHA224_fmt_plug.c
rawSHA256_fmt_plug.c
rawSHA384_fmt_plug.c
rawSHA512_fmt_plug.c

I mostly just put the mechanism in there, more can be done - especially 
for SHA-2 which currently only skip the final constant addition.
